about

Millions of years ago, the North American continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the Earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across Idaho. Generating cataclysmic volcaniceruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forcesstretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith andSiegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in fullcolor--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

Editorial Reviews

"The spectacular geysers and hot springs of Yellowstone are the world's best. They are in part the remains of a gigantic volcanic explosion 630,000 years ago that was a thousand times larger than the 1980 eruptions of Mount St. Helens. They also portend future volcanic action in this beautifulwonderland. Geologist Smith and science writer Siegel team up to tell the exciting story of how Yellowstone and Grand Teton National Parks came to be."--Bob Decker, former director of the U.S. Geological Surveys Hawaiian Volcano Observatory and Professor Emeritus, Dartmouth College, and BarbaraDecker, science writer
